Question

9. A helicopter flies west 200 miles in 2 hours, what is its velocity?​

Answer 1

Velocity = 100 miles per hour, WEST

Explanation:

Velocity and speed are very similar.

Speed is a scalar quantity, and velocity is a vector quantity.

The magnitude of speed and velocity are the same, just that velocity has a direction.

We can use basic distance formula to solve this. Which is:

D = RT

Where

D is the distance

R is the rate (speed or velocity)

T is the time

Given,

D = 200 miles

T = 2 hrs

Now, we want rate:

`D=RT\\200=R(2)\\R=(200)/(2)\\R=100`

The direction is WEST, thus we can say:

Velocity = 100 miles per hour, WEST
